While traveling at highway speeds, my 2017 GMC Yukon SLE suffered a sudden, catastrophic Active Fuel Management (AFM) valvetrain lifter and camshaft collapse. This caused an immediate and highly dangerous loss of vehicle propulsion in live moving traffic on I-95, creating an extreme physical safety hazard for my family. General Motors has extensive, documented internal corporate knowledge of this severe design defect under Technical Service Bulletin TSB #18-NA-073.

The paint on my hood, roof and mirrors has peeled off and the gray coating is showing. I have own many GM vehicles and have never had this happen before.

The daylight running light in the rear do not work, which is needed for night time driving. At night when parked or driving the rear is completely dark, except the license plate lights. When I press the brakes they turn on, the signal lights work even the reverse lights. I've switched them to manual mode still no luck. I've checked some fuses, they all check out, nothing blowen. From some research it's all conctrolled by the body control module. There are alot of cars with this same issue there should be a recall for gm to fix properly, dues to safety of the driver and public. We just bought this vehicle which, and didnt test drive at night. 3 days later we discovered it. We even bought new lights due to the number of complaints. They still don't work.

There has been 3 different incidents. First incident I was going 45mph merging into 5 lanes of traffic when the back of my driver seat randomly layed down flat and stayed there. I had to get off an exit, get out pull up on front of seat and then it layed back up. 2nd incident I was going about 40mph it folded completely forward and pinned me against the steeling wheel. I had to stop immediately in the middle of the road put my 4 ways on and wiggle and slide out of the car started pulling up on front of seat and was finally able to put it back in place. The 3rd time I was going 20 mph it folded completely forward and pinned against. Had to stop in the middle Of the road again pull up on front of seat. The lumbar setting randomly comes and goes while driving down the road. Took it the garage to be looked at. They weren’t able to figure out why it’s doing what it’s doing but the only option they had was to unplug the module for safety reasons

The recall repair for the brake vacuum pump did not hold for this vehicle. Even after the repair, several years later, the brakes would get hard as a rock, especially at low speeds and there was difficult stopping the vehicle. Due to the special Warranty on this recall, I was able to get the brake vacuum pump replaced at no cost. However, the recall repair failed initially. This is a safety issue.

Passenger brake Led Circuit board prematurely failed resulting in the entire assembly needing replacement. The assembly is $500 and higher. This is a safety issue and though there was a class action lawsuit, the light fails after 72000 miles which appears to be when GMC wont replace the part. $500 for a tail light replacement is a financial burden to be able to keep the car on the road. There is no warning when the light fails. Please consider a recall on the tail lights.
